BACKGROUND OF THE INVENTION Field of the Invention

One aspect of the invention relates to a food-holding tray for a household refrigeration appliance. The food-holding tray has at least one side wall. The food-holding tray additionally has at least one guide rail which is disposed on an external side of the side wall for coupling the food-holding tray to a tray-external guiding apparatus. In this way, the tray can be guided in a sliding movement. Further aspects of the invention relate to a guiding apparatus for a food-holding tray and a household refrigeration appliance.

A variety of food-holding trays, slidable in the depth direction and disposed in an accommodation space of a household refrigeration appliance, are known. A wide variety of guides therefor are also known. Reference may be made in this regard to European Patents EP 3 191 779 B1, EP 3 077 744 B1 and EP 3 030 853 B1, for example.

Desirable features in a food-holding tray are, on one hand, an advantageous guide and, on the other hand, easy handling for removal and insertion.

BRIEF SUMMARY OF THE INVENTION

It is accordingly an object of the invention to provide a food-holding tray with a rearwardly tapered guide rail, as well as a guiding apparatus and a household refrigeration appliance, which overcome the hereinafore-mentioned disadvantages of the heretofore-known trays, guiding apparatuses and appliances of this general type and in which the food-holding tray, in an embodiment with a laterally disposed guide rail for coupling to a corresponding guiding apparatus, can be slid easily, enabling improved coupling and decoupling with the guiding apparatus.

With the foregoing and other objects in view there is provided, in accordance with the invention, a food-holding tray for a household refrigeration appliance. The food-holding tray has at least one side wall. The food-holding tray also has a guide rail. The guide rail is disposed on an external side of this side wall. Through the use of the guide rail, the food-holding tray can be coupled to a guiding apparatus, which is disposed externally in relation to the tray and is not an integral part of the food-holding tray. In this way, the food-holding tray can be guided in a sliding movement.

The guide rail is tapered, viewed in the depth direction of the food-holding tray, in a rear end section. This rear end section is an integral part of the guide rail. This means that, viewed in the height direction, the guide rail therefore becomes narrower in this rear end section. An embodiment of this type creates a guide rail which on one hand enables reliable, non-jamming and steady guiding in the guiding apparatus. On the other hand, this end section narrowing in the height direction enables easy removal and insertion of the food-holding tray in the guiding apparatus. In this connection, tilting movements are also simplified.

In one exemplary embodiment, the rear end section is constructed as a hollow profile. This makes it possible to save weight. In particular, however, this provides further options for customizing the guide rail in order to enable further functionalities specifically in this rear end section. This makes it possible, in particular, for other components to be integrated in this rear end section and for their functionality in this respect to be developed.

In one exemplary embodiment, the rear end section has a ceiling surface. This may be the top of a roof wall of the end section. The roof wall in one exemplary embodiment delimits a hollow region of the end section. The hollow region may be a hollow cavity open to the side. An upwardly raised contact plateau is constructed on the ceiling surface. In one embodiment, this contact plateau is constructed in one piece with the roof wall. This contact plateau makes it possible to achieve a reduced area of contact between this upper region of the rear end section and the guiding apparatus. This enables smoother guiding. This makes it possible, in particular, for only the top of the contact plateau to be in contact with a roof wall of the guiding apparatus. In particular, easier tilting of the food-holding tray relative to the guiding apparatus, including in specific positions of the food-holding tray in the guiding apparatus, can be achieved in this way. The contact plateau forms an elevation in comparison to the rest of the ceiling surface, which advantageously enables this tilting movement and consequently the clearance between the roof wall of the guiding apparatus and the rest of the ceiling surface of the end section.

In one exemplary embodiment, the rear end section has a floor surface. The floor surface is a top of a floor wall of the end section. The floor wall delimits in particular the aforementioned hollow region of the end section from below. This floor surface features a recess over a part of its length measured in the depth direction. The recess is constructed as a continuous recess in the height direction. In one exemplary embodiment, this recess is constructed so as to be open on the side facing away from the side wall of the food-holding tray. It therefore forms, as it were, a recess that is open at the edge. Through the use of an embodiment of this type, a further element, namely this recess, is thus integrated into this rear end section. In operative connection with the guiding apparatus, this recess makes it possible to achieve movement configurations for the food-holding tray which enable reliable linear guiding to desired positions. On the other hand, this embodiment also makes it easy to achieve smooth movement of the guide rail over subcomponents of the guiding apparatus in other positions. This prevents unwanted bumping or jamming on them. In this connection, this recess thus then also forms a clearance or an opening upwards such that an element of the guiding apparatus can also in this respect project into it.

This element may for example be a stop of the guiding apparatus. The food-holding tray can in this way be pushed over a part of the distance of its sliding movement beyond a stop of the guiding apparatus projecting upwards in this manner without the stop coming undesirably into contact with the guide rail or generating in this regard an undesired stop. Even when an overlap in the depth direction between this guide rail and the stop of the guiding apparatus has already been reached, this does not undesirably cause any arresting or stopping of the food-holding tray. Only when a specifically defined position of the food-holding tray in the guiding apparatus has actually been reached can the effect of the stop then actually occur.

In one exemplary embodiment, the tapered configuration of the rear end section is formed by a roof wall of the rear end section being oriented, in particular fully, horizontally. In one exemplary embodiment, a floor wall of the end section, the floor wall being disposed below the roof wall in the height direction, is obliquely oriented. In particular, it rises from front to rear from a (viewed in the depth direction) front end, to a (viewed in the depth direction) rear end. As a result, the above-mentioned advantages in relation to the handling of the food-holding tray are particularly effective.

In one exemplary embodiment, the recess which is constructed in this floor wall ends at a front end of the end section. This is viewed in the depth direction of the food-holding tray. The recess consequently extends as far as this front end of the end section. In particular, the tapering of the end section begins at this front end of the end section. This configuration of the positional configuration of the recess also makes it possible for a stopping effect or an arresting effect of the food-holding tray to be generated at this front end when it is located in the guiding apparatus in a position in which the stop is in the region of the front end of the end section.

The recess is preferably constructed with a rear end, viewed in the depth direction of the food-holding tray. This rear end is not at the rear end of the end section. Viewed in the depth direction, the recess consequently does not extend over the entire length of the end section. In particular, it is shorter in relation thereto. The rear end of the recess is consequently forwardly offset relative to the rear end of the end section.

A height difference, measured in the height direction of the food-holding tray, between the front end of the recess and the rear end of the recess is greater than a height of a stop of the tray-external guiding apparatus on which the food-holding tray is configured to stop when it is slid linearly in relation to the guiding apparatus rearward in the household appliance or in the guiding apparatus. This is a further highly advantageous embodiment, since a functionally optimized and, in terms of spatial construction, improved system can be created in this way, as this makes it possible, when the food-holding tray is being slid relative to the guiding apparatus over a partial length with the guide rail, for the guide rail to be pushed beyond this stop of the guiding apparatus without this stop achieving its stopping effect. In particular, when the food-holding tray is being pushed back in the guiding apparatus, this rear tapered end section then slides partially beyond the upwardly projecting stop. The latter first passes below the guide rail and then dips into this recess during further rearward pushing of the food-holding tray.

This further relative movement, in which this stop of the guiding apparatus then engages through the recess at least partially in the guide rail and is then also located in the height direction such that it overlaps with this guide rail, takes place until the actual stop position is reached. The guide rail then stops with a delimiting wall against this stop. The front side of the delimiting wall directly adjoins the front end of the end section. The recess is closed directly at the front end by this delimiting wall.

In one exemplary embodiment, the contact plateau and this recess are disposed, viewed in the depth direction of the food-holding tray, such that they overlap with one another. This also makes it possible to achieve a compact and highly functional construction for guiding the movement of, in particular also for tilting, the food-holding tray, in a sliding position in which it has stopped against the stop of the guiding apparatus. In particular, in this stop position a simple construction for tilting the food-holding tray upward, in order to decouple it from the guiding apparatus, can then be implemented. In one exemplary embodiment, the contact plateau and the recess are disposed above one another in the height direction. They are spaced from one another in the height direction. They are separated from one another by a hollow region of the end section. They are integrated in different delimiting walls, in particular a roof wall or ceiling wall on one hand and a floor wall on the other hand.

In one exemplary embodiment, the height of the guide rail at a rear end of the tapered end section is between 40 percent and 60 percent of the height of a front end of the tapered end section. In this connection, an advantageous taper ratio is thus formed at the opposite (in the depth direction) ends of this end section. This promotes the above-mentioned advantages in terms of handling.

In one exemplary embodiment, the guide rail has a delimiting wall, at which a front end of the end section ends. This delimiting wall is a stop wall for stopping the guiding apparatus, which is constructed externally in relation to the food-holding tray. A secure and defined stop position of the food-holding tray is achieved in this way. The spatial assignment of this delimiting wall to the front end of the end section also supports in particular the movement guidance and freedom of movement of the stop. Nonetheless, secure stopping of this stop is enabled.

In one exemplary embodiment, the stop wall is an integral part of a framework structure of the guide rail. This construction means that the guide rail is of a material-saving and weight-reduced construction but on the other hand is mechanically very stable and able to withstand loads. The delimiting wall is in particular vertically oriented. It constitutes a rear delimiting wall of a further hollow cavity of the guide rail.

In one exemplary embodiment, the side wall, viewed in the height direction, has a lower region which is inwardly oriented. This may for example be at least in part a convex bulge. This means that, viewed from the storage space of the tray, the lower region bulges outwardly. The guide rail is disposed on the convexly bulging lower region on the external side thereof. This inwardly oriented region may also have in part a flat slanting wall. This would then be inclined relative to a vertical wall. In particular, the tray, viewed from above, is thus tapered toward the floor in this lower inwardly oriented region.

In particular, this guide rail is constructed in one piece with the side wall. In particular, the guide rail is disposed with its entire height inside the convexly bulging lower region. Such a construction makes it possible for the guide rail to project outwards in the width direction beyond the external side of the side wall such that a simple and secure coupling construction with the guiding apparatus is achieved. On the other hand, a hidden construction for the guide rail is achieved through the use of this explicit construction of the lower region of the side wall, namely of the convex bulge. With regard to the overall width dimensions of the entire side wall, one exemplary embodiment provides that the guide rail does not extend beyond the maximum width dimension of the food-holding tray. In particular, in an upper region which toward the top adjoins the lower region, the side wall is constructed toward the side such that the guide rail extends maximally to this width. Thus, in an exemplary embodiment, the guide rail does not project laterally and consequently in the width direction beyond the side wall. This applies to at least the front 60 per cent, in particular at least the front 70 per cent, in particular at least the front 80 per cent, in particular the at least front 90 per cent, of the length of the guide rail measured in the depth direction.

The side wall is preferably curved inwards in the rear region at least in this lower region. As a result, the tray is rearwardly tapered in the rear region.

In one exemplary embodiment, it is provided that a back wall of the food-holding tray, which toward the rear adjoins the side wall, is also constructed in a convexly bulging manner in a lower region. In particular, this is also provided on a second, further side wall opposite the first side wall of this food-holding tray. This results in a bulging, tub-shaped region in the lower region of the food-holding tray.

The food-holding tray preferably has a width (x direction is the width direction) of greater than or equal to 30 cm. In particular, the dimensional construction measured in the depth direction of the food-holding tray is greater than or equal to 30 cm.

With the objects of the invention in view, there is also provided a guiding apparatus for a household refrigeration appliance. The guiding apparatus is constructed for guiding a food-holding tray, in particular according to the above-mentioned aspect or an advantageous embodiment thereof. The guiding apparatus has a guide channel for mounting and guiding a guide rail which is disposed on an external side of a side wall of the food-holding tray. The guide channel has, viewed in the height direction, an upper ceiling surface. This is constructed as a top of a roof wall or ceiling wall. The guide channel has a floor surface of a floor wall disposed thereunder and spaced therefrom. In this guide channel, a stop is provided as a push-in stop for the guide rail. A functional compact construction is thus created, enabling easy guiding of the food-holding tray. A safe construction is created such that the food-holding tray cannot undesirably be pushed too far toward the rear. Undesirable bumping against a back wall of an internal container of the household refrigeration appliance is thereby avoided. An insertion position which is defined by the stop position is thereby always reliably achieved. In this position, however, the guide rail is still at least partially located inside the guide channel.

The guiding apparatus preferably has a stop which forms a pull-out stop. This stop is disposed in particular outside the guide channel. In particular, it is integrated on a floor wall of the guiding apparatus. When the tray is pulled out, a stop position is thus reached, so that the tray is prevented from tilting downward or falling down.

Starting from this reached stop position, the above-mentioned specifications of the food-holding tray in particular then also make it possible for the food-holding tray to be decoupled from the guiding apparatus. In order to do this, the food-holding tray can be raised in its front region. This is made possible in that, due to the contact plateau, which is preferably present, a clearance is formed to the front and to the rear, viewed in the height direction, between the underside of the roof wall of the guiding apparatus and the rest of the ceiling surface of the roof wall of the guide rail. This is also achieved by the tapered construction of the end section. In particular, the obliquely oriented floor wall of the guide rail contributes thereto.

In particular, the pull-out stop is a separate stop element from the push-in stop. The push-in stop is provided in connection with the pushing in of the food-holding tray so that no undesirable bumping of the food-holding tray, for example against a back wall of an internal container of the household refrigeration appliance, occurs. This internal container delimits the accommodation or receiving space of the household refrigeration appliance. In particular, the pull-out stop, which also constitutes a stop, is disposed outside the guide channel, but is positioned along the sliding path of the food-holding tray. In particular, it is disposed in a floor wall of the guiding apparatus, but is disposed in the depth direction in front of the front end of the roof wall of the guide channel. The described construction for removing and inserting the food-holding tray in the guide channel can thereby be improved.

In particular, the guide rail has a front delimiting wall which is constructed so as to be forwardly offset relative to the tapered end section. This further delimiting wall is for mechanically abutting against this pull-out stop of the guiding apparatus. In particular, the delimiting wall, which can for the purpose intended be brought directly into contact with the pull-out stop, and the other delimiting wall, which is provided for abutting against the push-in stop, are on one hand a front delimiting wall and on the other hand a rear delimiting wall of a hollow-cavity region of the guide rail.

With the objects of the invention in view, there is furthermore provided a household refrigeration appliance with a food-holding tray according to the above-mentioned aspect or an advantageous embodiment thereof.

In an exemplary embodiment, the household refrigeration appliance has a guiding apparatus according to the above-mentioned aspect. In the coupled state, the guide rail of the food-holding tray is guided in the guiding apparatus, in particular in the guide channel.

The guide channel of the guiding apparatus is oriented in the depth direction of the household refrigeration appliance. This enables a linear sliding movement of the food-holding tray in the household refrigeration appliance.

In an exemplary embodiment, the guiding apparatus is disposed on a separate plate of the household refrigeration appliance. This plate is in particular a compartment base. It can, however, also be a lid, for example. The lid can be an integral part of a keep-fresh system of the household refrigeration appliance. The keep-fresh system can, for example, be a keep-fresh container. This can have a tray and this lid. Food can thus be stored in this keep-fresh container with storage conditions which can be different from the rest of the accommodation space of the household refrigeration appliance. This accommodation space can, for example, be a freezer compartment of the household refrigeration appliance.

The specifications “top”, “bottom”, “front”, “rear”, “horizontal”, “vertical”, “depth direction”, “width direction” and “height direction” indicate the positions and orientations that apply when the tray or the appliance is being used and disposed as intended.

Further features of the invention will emerge from the claims, the figures and the description of the figures. The features and combinations of features referred to above in the description, as well as the features and combinations of features referred to below in the description of the figures and/or shown in the figures alone are usable not only in the combination specified in each case, but also in other combinations or in isolation, without departing from the scope of the invention. Consequently, embodiments of the invention which are not explicitly shown and explained in the figures, but which through separate combinations of features emerge and can be arrived at from the embodiments explained, shall also be deemed to have been covered and disclosed. Embodiments and combinations of features which consequently do not exhibit all the features of an originally worded independent claim shall also be deemed to have been disclosed.

Although the invention is illustrated and described herein as embodied in a food-holding tray with a rearwardly tapered guide rail, as well as a guiding apparatus and a household refrigeration appliance, it is nevertheless not intended to be limited to the details shown, since various modifications and structural changes may be made therein without departing from the spirit of the invention and within the scope and range of equivalents of the claims.

DETAILED DESCRIPTION OF THE INVENTION

Referring now in detail to the figures of the drawings, in which identical or functionally identical elements are denoted by the same reference characters,

and first, particularly, to FIG. 1 thereof, there is seen a diagrammatic representation of a household refrigeration appliance 1. The household refrigeration appliance 1 can be a refrigerator or a freezer or a combined refrigerator-freezer. The household refrigeration appliance 1 is constructed for storing and preserving food. The household refrigeration appliance 1 has a housing 2. The latter has an external housing 3. The housing 2 also has an internal container 4. The internal container 4 is accommodated in the external housing 3 which is separate therefrom. Thermally insulating material is inserted in an intermediate space between the internal container 4 and the external housing 3.

The internal container 4 has vertical side walls 5, 6, a ceiling wall 7, a back wall 8 and a floor wall 9. These walls 5 to 9 delimit an accommodation space 10 for food.

The household refrigeration appliance 1 also has a door 11, which is movably disposed on the housing 2. This accommodation space 10 can be closed by the door 11. The accommodation space 10 can be a refrigerated compartment.

FIG. 1 also shows a diagrammatic representation of a food-holding tray 12. This food-holding tray 12 is a separate component from the internal container 4. The food-holding tray 12 is non-destructively detachably removable from and re-insertable into the accommodation space 10. Furthermore, it is linearly slidable in this accommodation space 10 in the depth direction (z direction). Guiding apparatuses are provided for this purpose. These will be further explained below. In the exemplary embodiment, it can be provided that the household refrigeration appliance 1 has a keep-fresh container 13. This container 13 can have a tray 14 and a lid 15. In the exemplary embodiment, it is provided that the food-holding tray 12 is disposed on the keep-fresh container 13. In particular, the tray 12 is positioned on the lid 15 and is linearly horizontally slidably mounted thereon.

FIG. 2 shows a perspective representation of an exemplary embodiment of the food-holding tray 12. This food-holding tray 12 has a side wall 16 and an opposing further side wall 17. In addition, a back wall 18 and a floor wall 19 are provided. A front wall 20 is also provided. The food-holding tray 12 forms a food storage space 21 which is accessible from above.

The food-holding tray 12 preferably has a width (x direction is the width direction) of greater than or equal to 30 cm. In particular, the dimensional construction of the food-holding tray 12 measured in the depth direction is greater than or equal to 30 cm.

In the exemplary embodiment shown herein, the food-holding tray 12 is constructed in one piece. A longitudinal guide rail 23 is disposed on an external side 22 of the vertical side wall 17. This guide rail is constructed in one piece with the side wall 17. In the exemplary embodiment, the side wall 17 has an upper region 17 a. A lower region 17 b is constructed so as to adjoin this upper region 17 a directly at the bottom. This lower region 17 b is uneven. In this case in particular it is convexly bulging at least in regions. However, a different downwardly oriented tapering of the tray could also be provided. This guide rail 23 is integrated on this lower region 17 b on this external side 22. In height, it is constructed completely within this lower region 17 b. As can be seen, this guide rail 23 extends over at least 50 per cent, in particular at least 60 per cent, in particular at least 70 per cent of the dimensions of the side wall 17 measured in the depth direction. Viewed in the width direction, the guide rail 23 protrudes outwardly from the external side 22. Viewed in this width direction, the guide rail 23 does not, however, extend beyond the overall width of the side wall 17.

As can furthermore also be seen in FIG. 2, the back wall 18 also has a lower region 18 b, which adjoins an upper region 18 a. This lower region 18 b is also of a convexly bulging construction. The convex bulges of the lower regions 17 b and 18 b merge with one another. The side wall 16 corresponds in construction to the side wall 17. A guide rail 23 is likewise integrated on an external side of a lower region of the side wall 16.

As can be seen in FIG. 2, the guide rail 23 is constructed as a ribbed structure or framework structure. This means that it is not a bar of a solid and hollow-cavity-free construction. Rather, this elongated guide rail 23, which is oriented in the depth direction, is constructed with multiple hollow cavities.

Viewed in the depth direction, this guide rail 23 has a rear end section 24. This end section 24 is of a tapered construction. This means that a thickness measured in the height direction decreases, in particular continuously decreases, from a (viewed in the depth direction) front end 25 to a (viewed in the depth direction) rear end 26.

FIG. 3 shows in this connection an enlarged representation of a segment I in FIG. 2. This rear end section 24 can be seen. In addition, a roof wall 27 of the guide rail 23 is shown. A contact plateau 29 is constructed on a ceiling surface 28 of this roof wall 27. This contact plateau 29 is a raised sub-region which projects upwardly relative to the rest of the surface region of the ceiling surface 28. It extends in particular over the entire width of this roof wall 27. In one exemplary embodiment, the roof wall 27 is horizontally oriented. This means that in one exemplary embodiment it is not inclined relative to the horizontal plane.

Furthermore, the guide rail 23 has, in particular in the tapered end section 24, a floor wall 30 with a top which is a floor surface. The latter is constructed so as to be spaced in the height direction from the roof wall 27. As a result, the end section 24 is formed as a hollow-cavity profile.

In one exemplary embodiment, the floor wall 30 has a recess 31. The recess 31 is open at the edge. This means that it is constructed so as to be open on the side facing away from the external side 22. The floor wall 30 consequently has a non-uniform width due to this recess 31. The recess 31 has a front end 31 a. This end 31 a ends at the front end 25 of the end section 24. A rear end 31 b of the recess 31 is forwardly offset relative to the rear end 26 of the tapered end section 24. This means that a length of the recess 31 measured in the depth direction is less than the length of this tapered end section 24 measured in the depth direction.

It can furthermore be seen in FIG. 2 and FIG. 3 that the floor wall 30 is obliquely oriented. This means that, starting from its front end 25, it rises upwardly to its rear end 26. In particular, a continuous rise is provided for in this respect. Viewed in the height direction, the end section 24 is consequently narrowest at the rear end 26. It is thickest in this respect at the front end 25.

Furthermore, FIG. 3 also shows a delimiting wall 32. At the front, this delimiting wall 32 directly adjoins the tapered end section 24. The delimiting wall 32 is vertically oriented. It extends in the width direction over the entire width of the guide rail 23. Due to the construction with the recess 31, this delimiting wall 32 also forms a stop wall for a tray-external stop. The stop is in particular an integral part of a guiding apparatus. Due to the recess 31, the floor wall 30 is narrower at this front end 25 of the end section 24 than the delimiting wall 32. The delimiting wall 32 directly closes off the recess 31 on the front side.

Viewed in the depth direction, the delimiting wall 32 is a rear delimiting wall. It delimits a further hollow-cavity region 33 of the guide rail 23. Viewed in the depth direction, this hollow-cavity region 33 is delimited at the front by a further delimiting wall 34 (FIG. 2). This front delimiting wall 34 cannot be seen in FIG. 3. This front delimiting wall 34 also protrudes further outward in the width direction than the forwardly continued floor wall 30 of the guide rail 23.

FIG. 4 shows a perspective representation of an exemplary embodiment of a guiding apparatus 35. The guiding apparatus 35 is a separate component from the food-holding tray 12. The guiding apparatus 35 is constructed in this case as a rail. It has a base plate 36, which is of a strip-shaped construction. In this connection, the linear guiding apparatus 35 has a guide channel 37. When the food-holding tray 12 is coupled to the guiding apparatus 35, the guide rail 23 of the food-holding tray 12 is guided in this guide channel 37. This base plate 36 also in part forms a floor wall 38 with a top as the floor surface of this guide channel 37. Moreover, the guide channel 37 is delimited upwardly by a ceiling surface, in particular a roof wall 39. Outwardly, it is delimited at the side by a side surface, in particular a side wall 40. Inwardly, the guide channel 37 is constructed so as to be open over its entire length. Inside the guide channel 37, and thus inside the air space, which is delimited by the floor wall 38, the roof wall 39 and the side wall 40, a stop 41 is provided. The stop 41 is constructed in one piece with the guiding apparatus 35. It is constructed directly on the floor surface of the floor wall 38. It adjoins the side wall 40. The stop 41 is a push-in stop. This means that when the food-holding tray 12 is pushed in in the depth direction, the guide rail 23 abuts against it, thereby defining a push-in position. In particular, the lower delimiting wall 32, coming from the front, abuts against this stop 41. A rear push-in position of the food-holding tray 12 is thereby defined.

As is furthermore shown in FIG. 4, a downwardly projecting contact plateau 39 a is provided on the ceiling surface. The contact plateau 39 a is constructed in the front region of the roof wall 39. This contact plateau 39 a is a tilt protection for the food-holding tray 12 when the latter is pulled relatively far forward in relation to the guiding apparatus 35. In particular, the contact plateaus 29 and 39 a can then also rest against one another. In particular, the food-holding tray 12 can thereby be held horizontally, in particular in the pull-out position shown in FIG. 7.

In particular, the contact plateau 29 does not rest directly against the ceiling surface when the food-holding tray 12 is in a position in which the contact plateaus 29 and 39 a do not overlap in the depth direction. In particular, a small air gap is then formed.

In particular, the guiding apparatus 32 has a further stop 42. This further stop 42 is provided on the base plate 36. In particular, it is constructed in one piece therewith. This additional front (viewed in the depth direction) stop 42 is disposed outside the guide channel 37. It is forwardly offset relative to this guide channel 37. This further stop 42 forms a pull-out stop for the food-holding tray 12. When the food-holding tray 12 is pulled out and consequently when the food-holding tray 12 is pulled forward relative to the guiding apparatus 35, the preferably present front delimiting wall 34 coming from the rear stops against this further stop 42.

In particular, the guiding apparatus 35 is constructed as a one-piece component, in particular made of plastic.

The guiding apparatus 35 can, as shown in the perspective representation in FIG. 5, be part of a configuration 43. The configuration 43 can include the guiding apparatus 35 and a plate 44 separate therefrom. The plate 44 can be a partition wall or a compartment base. The plate 44 can, however, also be a lid of a keep-fresh container. In particular, the plate 44 can be the lid 15.

As can be seen in FIG. 5, two guiding apparatuses 35 are provided in this case on opposite sides. They are in particular non-destructively detachably disposed on the plate 44. They can be disposed for example so as to be snapped thereon. However, a non-destructively detachable configuration of the guiding apparatuses 35 on the plate 44 can also be provided.

FIG. 6 shows a configuration 45 in which the food-holding tray 12 is disposed on the configuration 43. In particular, a mechanical coupling is implemented in this case between the guide rail 23 or the guide rails 23 disposed respectively on the external sides of the opposing side walls 16 and 17 and the two guiding apparatuses 35.

As can be seen in this connection, the side wall 17 has, viewed in the depth direction, in particular also in the lower region 17 b, not only a bulge downwards, but also a bulge 17 c in the width direction inwards. This can also be seen in the plan view of the food-holding tray 12 in FIG. 12. This therefore means generally speaking that the side wall 17, in particular also the opposing further side wall 16, bulges downwardly in the lower region and also, viewed in the width direction, bulges inwardly in the rear region.

FIG. 7 shows a perspective vertical sectional representation of the system or the configuration 45 according to FIG. 6. In this case, a sectional representation in the region of the guide rail 23 is shown, but nearer to the side wall 17, so that the recess 31 is not yet intersected. Furthermore, the food-holding tray 12 is shown in a maximum pull-out position. This means, as has already been explained above, that the front delimiting wall 34 coming from behind has stopped on the front stop 42. In this pull-out position, this front stop 42 serves as a pull-out stop. The guide rail 23 is disposed at least with its end section 24 still inside the guide channel 37 when this pull-out position is reached at the pull-out stop. As can be seen, the contact plateau 29 rests against the underside of the roof wall 39. It therefore rests against the ceiling surface of the roof wall 39. A reduction in tilting is achieved in this way.

FIG. 8 shows a perspective sectional representation corresponding to that shown in FIG. 7. The food-holding tray 12, however, starting from the pull-out position reached in FIG. 7, is raised upward or tilted upward in the front region. This is enabled by the tapered construction of the end section 24. It can be seen herein that the floor wall 30 of this end section 24 sits on the floor surface of the floor wall 38. This upward tilting achieves, in the region of the front delimiting wall 34, a lifting height which is greater than the height, viewed in the height direction, of the front stop 42. In this upwardly tilted position, the food-holding tray 12 can thus be obliquely forwardly pulled out of and inserted into the guide channel 37.

In this regard, an enlarged representation of a segment II in FIG. 8 is shown in FIG. 9. FIG. 8 and FIG. 9 show, in this connection, a different vertical sectional plane from that in FIG. 7. A section is shown herein in the region of the recess 39.

FIG. 10 shows a vertical sectional representation of the configuration 45. In this case, the food-holding tray 12 is shown in a pushed-in end position. It can be seen in this regard that the rear delimiting wall 32 coming from the front rests against the stop 41 of the guiding apparatus 35. Further rearward pushing of the food-holding tray 12 is therefore not possible.

FIG. 11 shows in turn an enlarged representation of a sub-region III in FIG. 10. As can also be seen in FIG. 11, the height h1 of this rear stop 41, measured in the height direction, is less than a height difference measured in this height direction between the bottom edge 25 a of the front end 25 of the end section 24 and a bottom edge 31 c of a rear end 31 b of the recess 31. This means that at this rear end 31 b the tapering of the end section 24 is such that when the guide rail 23 coming from the front is pushed beyond the rear stop 41, no mechanical contact thereof with the stop 41 hindering the sliding occurs. When the food-holding tray 12 is pushed beyond it, the stop 41 consequently dips contactlessly into the recess 31. In spite of the tapered construction of the end section 24, the stop 41 consequently does not hit the floor wall 30. In this respect, this recess 31 also serves as a clearance for sliding in and guiding the end section 24 beyond the stop 41 unhindered.

FIG. 12 shows the food-holding tray 12 from above. The side walls 16 and 17, which in the rear region run inwardly in the width direction, can be seen. This inward bulge 17 c is implemented in the embodiment shown herein not only in the lower region 17 b, but also in the upper region 17 a.

FIG. 13 shows a side view of an exemplary embodiment of the food-holding tray 12. It can be seen that the tapered end section 24 extends in the regions 17 b and 17 c.
